pucCreate

Creates a puc-file ("portable unaggregated collection") for a collection that was already computed via retrieveData (e.g. with puc = FALSE, or where a puc could not be created at the time, for example due to strict mode). This makes it possible to create a puc-file for an existing archive without having to rerun the underlying calculations.

Usage

pucCreate(archive, pucName = NULL)

Arguments

archive: path to a tgz-file as created by retrieveData
pucName: (Optional) name (without the .puc extension) the puc-file should be given. Only needed for archives created before retrieveData started recording this name in config.rds.

Value

Invisibly, the path to the created puc-file.

Note

This only works as long as the madrat cache files that were used to compute the archive are still available on this machine, as the archive itself only contains the aggregated collection, not the underlying cache files. If some of these cache files are missing pucCreate will fail with an error naming them.
